1. Tus cawv ntawm cov txheej txheem kev kho ntawm kev lag luam ntawm kev lag luam txhuas
Txhawm rau kom tau txais kev kub siab ua kom muaj zog ua kom muaj zog ntxiv, qhov kev ua cua sov quenching yuav tsum tau ntev dua thiab kev ua kom muaj kev vam meej uas tau txais cov kev daws teeb meem ntau tshaj; Ib qho ntxiv, theem ob tsis tuaj yeem yog precipitated thaum lub sij hawm quenching, txwv tsis pub nws yuav ua rau muaj kev tsis xwm yeem hauv ib cheeb tsam thiab kev ua kom muaj kev kub ntxhov.
2. Qhov regression prenomenon ntawm kev muaj khoom txhuas aluminium
Nyob rau hauv lub tswv yim, kev kho mob regression yog tsis txwv los ntawm cov kev kho mob, tab sis nyuaj rau kev kho nag lossis daus, uas maj mam ua kom muaj zog ua kom muaj zog. Yog li ntawd, kev kho kom zoo yog siv rau kev kho cov rivet alloys siv nyob rau hauv cov dav hlau, thiab nws muaj tus nqi siv me me rau lwm yam kev lag luam txhuas.
3. Tus cawv ntawm kev laus kub
Thaum cov laus ntawm ntau qhov kub, qhov tseem ceeb, muaj pes tsawg leeg, thiab sib sau ua ke ntawm theem kub yog qhov sib txawv. Yog tias qhov ntsuas kub tsawg dhau, lub gp cheeb tsam tsis yooj yim los tsim vim nyuaj diffusion, thiab lub zog thiab hardness thiab hardness tom qab kev laus tsawg, thiab kev laus siab dhau lawm. Thaum nws yog siab, diffusion yooj yim mus ua tiav, qhov tseem ceeb siv lead ua ke ntawm cov khoom siv nag lossis tawv me me, thiab lub siab tawv tom qab kev laus tsawg, yog, hla kev tshwm sim.
4. Tus cawv ntawm cov tshuaj lom neeg muaj pes tsawg leeg ntawm kev lag luam txhuas
Txawm hais tias ib qho kev ua kom muaj zog los ntawm kev laus nyob ntawm seb cov ntsiab lus uas ua rau cov alloy tuaj yeem ua rau cov solubility hloov nrog ntsuas kub. Piv txwv li, cov solubility ntawm silicon thiab manganese hauv txhuas yog me me thiab tsis hloov ntau nrog kub. Txawm hais tias Magnesium thiab Zinc muaj ntau dua cov solubility nyob rau hauv aluminium {2} Qhov txawv yog tsis loj thiab muaj txiaj ntsig yog tsawg heev.
